FEEdEr dOES NOT FEEd
1. No pellets in hopper.
2. Firebox draft may be too low for low draft pres-
sure switch in feeder circuit to operate. Check
for improperly closed doors, loose or missing
gasket on doors or hopper lid, or a faulty pres-
sure switch.
3. Feed motor will not run until the ESP
senses 170 deg. F. Maybe you did not put
enough pellets in the burn pot before lighting the
fire manually.
4. Something is restricting flow in the hopper or
causing the slide plate to stick.
5. Feed motor has failed.
PArTIAllY burNEd PEllETS
1. Feed rate too high.
2. Draft too low. (Check burn pot clean-out slide
and door gasket).
3. Burn pot or heat exchanger tubes may need
to be cleaned.
4. Combination of all the above.
5. #6 status blink: A 6 blink control board sta-
tus indication is caused by poor or incomplete
combustion. The Automatic Ignition circuit board
has the ability to track the combustion through
feed settings and ESP temperatures. when the
control board has calculated poor or incomplete
combustion, it will shut down the unit as a safety
feature. (Poor or incomplete combustion is a
contributer of creosote which may cause a chim-
ney fire)
A 6 blink status may be caused by several
things:
1. Blocked or partially blocked flue.
2. Blocked or partially blocked inlet air.
a. Backdraft damper on the inlet pipe may be
stuck closed.
b. If outside air is installed, the inlet cover may
be blocked.
3. The air chamber under the burnpot may be
filled with fines and small bits of ash.
4. The holes in the burnpot may be getting filled
with ash or carbon buildup.
5. Combustion blower fan blades may need
cleaned.
6. There is no fuel in the hopper.

4. Combination of 1 and 2.
Cleaning burn Pot
whenever your boiler is not burning, take
the opportunity to scrape the burn pot to remove
carbon buildup. A vacuum cleaner is handy to
remove the residue. be sure the boiler is cold if
you use a vacuum.
Carbon buildup can be scraped loose with
the fire burning using the special tool provided
with your stove. Scrape the floor and sides of the
burn pot. The carbon will be pushed out by the
incoming fuel. Always wear gloves to do this.
removing Ashes
Ashes can be removed while in operation,
but extra care must be taken and always wear
gloves.
Maximum Feed Adjuster settings are not
needed in most cases. Operating in the normal
range (#4) is recommended when maximum heat
output is not required. The ESP prevents the
stove from being over-fired.
Keep the boiler free of dust and dirt.
Fuel
Pellet fuels are put into 3 categories in terms of
ash content. Premium at 1% or less, Standard at
3% or less and all others at 3% or more.
This unit is capable of burning all 3 categories
of pellets due to a patented feeder and burn pot
system.
It should be noted, however, that higher ash
content will require more frequent ash removal,
scraping of the burn pot, and may provide less
BTU’s per pound. Normally, standard and high ash
pellets cost less than premium pellets and can be
cost effective when burned in this boiler.
The moisture content must not exceed 8%.
Higher moisture will rob BTU’s and may not burn
properly.
